CA 2494016

There is provided a fluid dispenser (5, 105, 205, 305, 405) having a housing (9, 109, 209, 309, 409) and a pump action fluid discharge device (8, 108, 208, 308, 408). The pump action fluid discharge device (8, 108, 208, 308, 408) is arranged to be actuated by one or more levers (20, 21, 120, 220, 221, 320, 321, 420, 421) which are pivotally supported within the housing (9, 109, 209, 309, 409). When the or each lever (20, 21, 120, 220, 221, 320, 321, 420, 421) is rotated about its lower end the fluid discharge device (8, 108) is urged towards a nozzle (11, 111, 211, 311, 411) causing a single dose of fluid to be dispensed from the nozzle (11, 111, 211, 411). Various mechanisms are proposed for converting the transverse application of force from each lever (20, 21, 120, 220, 221, 320, 321) into a force along a longitudinal axis of the fluid discharge device (8, 108, 208, 308, 408).

L'invention concerne un distributeur de fluide (5, 105, 205, 305, 405) comprenant un logement (9, 109, 209, 309, 409) et un dispositif de décharge de fluide à pompe (8, 108, 208, 308, 408). Le dispositif de décharge de fluide à pompe (8, 108, 208, 308, 408) est conçu pour être actionné par un ou plusieurs leviers (20, 21, 120, 220, 221, 320, 321, 420, 421) montés de façon pivotante dans le logement (9, 109, 209, 309, 409). Lorsqu'un ou plusieurs des leviers (20, 21, 120, 220, 221, 320, 321, 420, 421) sont actionnés et tournent autour de leur extrémité inférieure, le dispositif de décharge de fluide (8, 108) est amené vers un embout (11, 111, 211, 311, 411), ce qui entraîne la distribution d'une dose unique de fluide par l'embout (11, 111, 211, 311, 411). Plusieurs mécanismes sont proposés pour transformer l'application transversale de la force de chaque levier (20, 21, 120, 220, 221, 320, 321) par une force orientée selon l'axe longitudinal du dispositif de décharge de fluide (8, 108, 208, 308, 408).
